T0 @ZZ whom t may concern:

Be it known that I, CHRISTIAN Z. F. Rorr, a resident of Pittsburg, inthe county of Allegheny and State of Pennsylvania, have invented a newand useful Improvement in Apparatus for Finishing Articles of Glassware;and I do hereby declare the following to be a full, clear, and exactdescription thereof.

My invention relates to apparatus for firepolishing articles ofglassware.

The object of my invention is to provide a simple form of apparatus ofthis character which will convey the articles of glassware fed theretoto the proper position with reference to the heating-furnace and theremanipulate said article in such a manner as to firepolish it thoroughlyand convey it away without the employment of any labor other than thatrequired to feed and operate the machine.

To these ends my invention comprises the novel construction set forth inthe specification and claims which follow.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure l is an end view in elevation of my improved apparatus.Fig. 2 is a vertical cross-section on line 2 2, Fig. l. Fig. 3 is a planview. Fig. 4 is a diagrammatic view of the movements of the transferringmechanism. Fig. 5 is an enlarged detail View of the supporting-rollersand mechanism for adjusting the same. Fig. 6 is a modified form ofsupporting-rollers.

Like letters indicate like parts in each of the figures.

The letter A designates a suitable frame for supporting the apparatus.Extending out from the frame A is the bracket a, in which is journaledthe shaft af. Secured to the outer end of the shaft a is the hand-wheela2, by means of which said shaft is revolved. This shaft ct may,however, be operated by other than hand-power. A sprocket-wheel b ismounted on the inner end of the shaft Ct', and a sprocket-chain b'connects said wheel with the sprocket-wheel b2 on the shaft b3 in thehanger A', depending from the frame A. A gear-wheel c on the shaft b3meshes with the pinions c c2 on the shafts c3 c4, respectively,journaled in the hanger A.

Secured to the ends of the shafts c3 c4 are the cranks cl CW,respectively. The crankpins d2 connect said cranks with the rods ee. Theupper ends of the rods e e' have the arms e2 e3, extending in oppositedirections, said arms having the forks f f or other lifting means.Secured to the shaft c3 is the eccentric weight.

Mounted on the frame A are the guideboxes h h', which act as supportsand guides for thel Shanks 2 of the bifurcated bearings if 'i'. Mountedon shafts 1 in said bearings t 1l' are the supporting-rollers l Z. Theserollers may vary in shape and size according to the shape of thearticles they are to support. Adj Listing-screws m pass up throughthreaded openings in the angles m' on the frame, and said screws areadapted to engage the shanks t2, whereby the bearings t t" may be raisedor lowered, as desired.

In order to provide for the turning of the Shanks t2 and the adjustmentof the rollers at dierent angles with reference to each other, I providethe adjusting-screwn, which passes though the swivels n', supported bythe lugs n2 on the bearings t' t. The screw 'n is contracted at aboutits mid-point, as at n3, said contracted portion bearing against a lugo. The screw n has right and left hand threads thereon. It is apparentfrom the above that by turning the screw n the rollers l may be movedaway from each other and the rollers Z brought correspondingly nearer,or vice versa, according to the size and shape of the article to besupported thereon.

Beyond the rollers ZZ are the receiving-rollers r fr', the rollers fr,together with the adjacent rollers Z Z', acting as a support for thearticle when it is first received in the apparatus and the rollers r/acting to receive it as it passes beyond the furnace.

Extending out from the frame A isthe bracket s,within which is journaled the powerdriven pulley s'. An endless belt s2 passes from thepulley s up under -the pulley s3, up over the pulley s4, thence downunder pulley S5, up over pulley s6, and down under pulley .S7 to thepulley s. Through power imparted IOOv in this manner the rollers Z Z'are made to revolve in the same direction.

Supported on tracks t on the frame A are the furnaces t', said furnacesbeing of any suitable construction, with refractory lining, and havingthe glory-holes t2 facing each other. The furnaces are mounted on thewheels Z8, which ride on the track i. Gas-supply pipes u enter thefurnaces from below and furnish fuel thereto. Gas is admitted to saidpipes by the openings u', s'aid openings being connected up by flexiblepipe with the main supply. The glory-holes Z2 are preferably contractedin the form of segmental slots, as shown, and project up ata slightangle in order to direct the heat more effcctually onto the object to behre-polished. Furthermore, a recess or depression t4 is formed in theface of the furnace, Which forms a kind of pocket to retain the heataround the object.

To provide for the movement of the furnaces over the tracks toward andfrom each other, the treadles or foot-levers w are provided. Thefoot-levers are connected bythe links 'w' with the levers 102, pivotedin the hangersw. Secured to the levers 2v2 are the arms which carry attheir upper ends the hooks These hooks 5U' engage with openings in therings x2, surrounding the pipes u.. It is apparent from the above thatby depressing the foot-levers w the furnaces will move away from eachother and that by raising said foot-levers they will approach each otherfor the purposes more fully hereinafter set forth.

I Will now describe my improved apparatus as applied to thefire-polishing of lamp-chimneys, although its use may be extended to allother articles of glassware to which it may be found applicable.

The lamp-chimney y to be fire-polished is placed upon thereceiving-rollers r, the rollers ZZ having been previously adjusted bythe adj Listing-screws m n to correspond to the shape and size of saidchimney. The distance between the furnaces t is also previously arrangedby means of the foot-levers w, so as to bring the ends of said chimneyin proper proximity to the glory-holes to give the requisitenre-polishing effect thereto. The operator then grasps the hand-wheel a2and proceeds to rotate same. This rotation of the said wheel through thegearing mechanism operated thereby will cause the rods e e' to rise. Thearms ve2 thereof ascending in line with the ends of the chimney y will,through Vthe forks f, lift the chimney from the rollers. These forksthen support the chimney at its base and neck. As the hand-wheelcontinues to revolve the rods e e', asshown in the diagrammatic viewFig. 4, ascend slightly farther, moving over toward the rollers ZZ atthe same time. When the highest point has been reached, said rods beginto descend in the same manner, moving toward the rollers Z Z', untilthey deposit the chimneybetween the said rollers, so that it issupported thereon. The rods then descend out of the way. The chimney isnow supported on the revolving rollers Z Z', with its ends in closeproximity to the gloryholes. The segmental slots t2, which form theglory-holes, direct the heat radially, and the ends of the chimney beingon substantially the same curve a greater portion of the same issubjected to the heat, while at the same time the depressions t4 tend toform pockets for the heat and less heat is wasted. After the chimney hasbeen allowed to revolve in this manner the requisite time to remove anyunevenness or roughness on its ends and has been properly fire-polishedthe operator again turns the hand-wheel d2, when the rods e e follow thesame course as before, the arms e3 moving so as to brin g their forks upunder the chimney fz/ to lift it from the rollers and deposit it on thereceiving-rollers r'. The arms e2 by the same movement have lifted asecond .chimney from the roller r and placed it on the revolving rollersZ Z in the same manner as before. In this manner the machine is keptoperating continuously, so that each time a chimney is removed from therevolving rollers another takes its place.

The construction shown and described may be modied and varied Withoutdeparting from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-
